Car emissions claims

Leigh Day are leading experts in vehicle emissions group claims.

Volkswagen emissions claims

Leigh Day are joint-lead lawyers in the emissions litigation on behalf of UK Volkswagen owners, who recently won the first round of their emissions case against Volkswagen in the UK High Court.

Leigh Day argued that Volkswagen had deceived car owners as to the compliance of vehicles with EU Emissions Regulations. Lawyers for the UK drivers argued that Volkswagen engines contained defeat device software which sensed when the vehicle was being tested and so artificially reduced emissions in order to pass that test.

Volkswagen have always argued that the software did not meet the legal definition of a defeat device and so was not illegal.

However, in April 2020 the High Court in London found that the decision by the KBA, the German road vehicle authority, that the software was a ‘defeat device’ was binding in the English High Court.

The court also agreed that the fact that the engine operates in different modes during the emissions test means that it contained a ‘defeat device’ under the EU emissions Regulations.

Mercedes claims

We are investigating a potential group claim against the German car manufacturer Mercedes-Benz over the use of an alleged ‘cheat device’. If you own a Mercedes-Benz AdBlue vehicle, you could be entitled to compensation
